PlaneBoundary

Container for the boundary of a detected planar surface. This is specific to Magic Leap because the polygon describing the boundary may be concave, and may contain holes.

Inherits from:
IEquatable< PlaneBoundary >

Public Fields

holeCount

The number of holes in this boundary.

public int holeCount { get; set; }

---

polygonVertexCount

The number of vertices in this boundary's polygon.

public int polygonVertexCount { get; set; }

---

valid

Whether this PlaneBoundary is valid. You should check for validity before invoking GetPolygon(Allocator, NativeArray<Vector2>), GetPolygon(Allocator), GetHole(int, Allocator), or GetHole(int, Allocator, NativeArray<Vector2>).

public bool valid { get; set; }

Returns: true if obj is of type PlaneBoundary and compares equal with Equals(PlaneBoundary).

---

bool Equals

IEquatable interface. Compares for equality.

public bool Equals(
    PlaneBoundary other
)

Parameters

Type	Name	Description

Returns: true if all fields of this PlaneBoundary compare equal to other .

---

override int GetHashCode

Computes a hash code suitable for use in a Dictionary or HashSet .

public override int GetHashCode()

Returns: A hash code suitable for use in a Dictionary or HashSet .

NativeArray< Vector2 > GetHole

Get the polygon representing a hole in this boundary. The 2D vertices are in plane-space.

public NativeArray< Vector2 > GetHole(
    int index,
    Allocator allocator
)

Parameters

Type	Name	Description
int	index	The index of the hole. Must be less than holeCount.
Allocator	allocator	The allocator to use for the returned NativeArray. Must be Allocator.TempJob or Allocator.Persistent .

Exceptions:

• System.InvalidOperationException Thrown if valid is false.
• System.InvalidOperationException Thrown if _allocator_ is Allocator.Temp or Allocator.None .
• System.ArgumentOutOfRangeException Thrown if _index_ is less than 0 or greater than or equal to holeCount.

Returns: A new NativeArray allocated with allocator containing a set of 2D vertices in plane-space describing the hole at index .

---

unsafe void GetHole

Get the polygon representing a hole in this boundary. The 2D vertices are in plane-space.

public unsafe void GetHole(
    int index,
    Allocator allocator,
    ref NativeArray< Vector2 > polygonOut
)

Parameters

Type	Name	Description
int	index	The index of the hole. Must be less than holeCount.
Allocator	allocator	The allocator to use if _polygonOut_ must be resized. Must be Allocator.TempJob or Allocator.Persistent .
ref NativeArray< Vector2 >	polygonOut	The resulting polygon describing the hole at _index_ .

Exceptions:

• System.InvalidOperationException Thrown if valid is false.
• System.InvalidOperationException Thrown if _allocator_ is Allocator.Temp or Allocator.None .
• System.ArgumentOutOfRangeException Thrown if _index_ is less than 0 or greater than or equal to holeCount.

---

unsafe void GetPolygon

Gets the polygon representing a plane's boundary, and, if successful, copies it to polygonOut . polygonOut is resized or created using if necessary. The 2D vertices are in plane-space.

public unsafe void GetPolygon(
    Allocator allocator,
    ref NativeArray< Vector2 > polygonOut
)

Parameters

Type	Name	Description
Allocator	index	The index of the boundary to retrieve.
ref NativeArray< Vector2 >	allocator	The Allocator to use if _polygonOut_ must be recreated. Must be Allocator.TempJob or Allocator.Persistent .
	polygonOut	A NativeArray to fill with boundary points. If the array is not the correct size, it is disposed and recreated.

Exceptions:

• System.InvalidOperationException Thrown if valid is false .
• System.InvalidOperationException Thrown if _allocator_ is Allocator.Temp or Allocator.None .

---

NativeArray< Vector2 > GetPolygon

Gets the polygon representing this boundary. The 2D vertices are in plane-space.

public NativeArray< Vector2 > GetPolygon(
    Allocator allocator
)

Parameters

Type	Name	Description
Allocator	allocator	The allocator to use for the returned NativeArray. Must be Allocator.TempJob or Allocator.Persistent .

Exceptions:

• System.InvalidOperationException Thrown if valid is false .
• System.InvalidOperationException Thrown if _allocator_ is Allocator.Temp or Allocator.None .

Returns: A new NativeArray containing a set of 2D points in plane-space representing a boundary for a plane. The caller is responsible for disposing the NativeArray.
